APPARATUS FOR COOLING AIR.

SPECIFICATION forming part of Letters Patent No. 586,766, dated July 20, 1897. Application filed October 14, 1895. Serial No. 565,613. (No model.)

-ratus for Cooling Air, of which the following is a specification.

According to this invention air to be circu lated through rooms or stores is brought into contact with fined vertical diaphragms cooled by being constantly wetted on both sides with brine or some uncongealable liquid. For this purpose I use a number of vertical corrugated metal plates continuously supplied at the top with brine or other uncongealable liquid and and having their bottoms in or above a re- 1 drive a current of air by means of a fan or blower through the spaces between the plates. The air being divided by the corrugated plates into a number of thin sinuous currents is cooled in its passage between the plates by impinging on them and the cold fluid trickling down the sides of each plate.

Figure l of the accompanying drawings is a plan of the apparatus, and Fig. 2 is a vertical section.

A is the receiver, in which the brine is cooled to a low temperature by the coils of pipe B or otherwise.

0 is the fan or blower.

D is the pump, by which the liquid is raised t0 the upper tank E.

F F are the corrugated plates, and G G are k the distance-pieces between them.

G G are inclined lugs on the distancepieces, which alone come in contact with the plates, leaving narrow inclined slits-0r passages G for the liquid. The upper distancepieces have projections G which together form the ends of the trough E, packing being bolts H.

' J is a trough with a perforated bottom for distributing the brine in the trough E.

. The plates should be as near together as is practicable without injuriously checking the flow of air.

Flat plates or plates with horizontal corrugations may be employed instead of plates The disso. advantageously, because the air can pass between them in a straight line instead of being compelled to wind backward and forward between the corrugations and impinge again and again against the cold liquid and the surfaces of the plates.

Having now particularly described and ascertained the naturepf my said invention and in what manner the same is to be performed, I wish it to be understood that I do not claim generally apparatus in which air is cooled by being passed over plates wetted with cold brine, which I am aware has alreadybeen done disadvantages; but

What I claim is 1. The combination of a number of fixed vertical plates, distance-pieces between the tops of the plates forming the perforated bottom of a trough, means for supplying cold brine or other uncongealable liquid to the trough and means for carrying the air or gas between the plates.

I 2. The combination of a number of fixed vertically-corrugated plates, distance-pieces between the tops of the plates forming the perforated bottom of a trough, means for'supplying cold brine or other uncongealable liquid to the trough and means for carrying the air or gas between the plates.

3. The combination of a number of fixed vertical plates, distance-pieces between the tops of the plates forming the perforated bottom of a trough, means for supplying cold brine or other uncongealable liquid to the trough, means for carrying the air or gas between the plates, and a receiver for the cold liquid into which the bottoms of the plates dip.
